On the other hand, actually there are various updated versions of bit threads, which are very useful tools for studying various aspects of the relationship between geometry and quantum entanglement, such as the covariant bit threads [1]}, the quantum bit threads [2]}, [3]}, the Lorentzian bit threads [4]}, [5]}, the hyperthreads [6]}, [7]}, etc. It is likely that our thread/state correspondence rules could be further adapt to these similar objects and lead to deeper or clearer understandings of these different important aspects of the holographic duality.
